Part Number: TMP421 Other Parts Discussed in Thread: DXP , Hi,
The TMP421A reads temperature from the remote sensor, and the obtained values are all negative. We have tried swapping resistor and capacitor positions and values as per the datasheet, but it…
Part Number: TMP421 Other Parts Discussed in Thread: TMP441 Hi Expert,
My customer is currently using TMP421AIDCNR and they want to added TMP441AIDCNR as an alternative.
Do these two part can fully replaced each other without any BOM change and application…
Part Number: TMP421 Other Parts Discussed in Thread: DXP For the TMP421, the data sheet states "If the remote channel is not utilized, DXP can be left open or tied to GND." However, nothing is stated about the DXN pin. How shall I connect the…
Ren,
Ren Schackmann said: The TMP421 should NACK attempts to write to these registers, even if they are writes that would otherwise disable beta compensation on TMP441.
Will the TMP421 return NACK for read attempts to those registers, too?
Best regards…

Part Number: TMP421 Other Parts Discussed in Thread: TMP441 , TMP442 , TMP423 , TMP422 Hi
Please suggest TMP421AIDCNR I2C Remote and Local Temp Sensor SOT23-8 "p2p" 2nd source
Part Number: TMP421 I have three questions regarding the TMP421:
1. If I want to read the temperature regularly do I have to check the BUSY signal before reading or is it enough to wait a certain amount of time and then just read? If the latter, how much…
Part Number: TMP421 I see the TMP421 contains registers. What type of memory is used to store those registers (ie SRAM, DRAM, EEPROM, Flash, etc.)? In particular, I am interested to know if these registers are volatile or non-volatile.
Part Number: TMP423 Other Parts Discussed in Thread: TMP421 I want to use TMP423 to replace TMP421.
Is it okay to connect pin3 and pin4 of TMP423 to GND? If there is a problem, please tell me the connection destination of pin3 and pin4 of TMP423.
